This is a knit hat for dogs with ear holes. It's made with a combination of 100% salmon pink wool and three strands of bulky yarn, knitted to be fluffy, warm, and durable. The face and neck are ribbed, and the crown is stockinette stitch. It's long, so it covers the neck like a snood. To ensure a comfortable fit, it's made with soft, stretchy, and skin-friendly wool blend yarn using knitting needles. Although crochet hats can be made faster, they tend to be stiff and not very stretchy, so I've chosen to use knitting needles even though it takes more time. I've been making knit hats for dogs for 5 years, and I knit each stitch carefully, hoping your dog will stay cute and warm. ■ Size Face circumference: 36cm - 40cm Please measure the circumference of your dog's head, from the base of one ear, across the forehead, under the chin, and back to the starting point. ■ Materials Main body: 100% wool, and a combination of 100% wool and 70% wool/30% acrylic Pom-pom: Acrylic, wool blend Please note that this is a handmade item and is not perfect like commercially available products. While I knit each one carefully, there may be some loose thread ends or slight irregularities in the stitch pattern. Knit products may unravel or tear if pulled strongly or subjected to impact. Please wash by hand in lukewarm water and avoid wringing. Since it will stretch if hung, remove excess water with a towel and dry flat. It will be shipped via Yu-Packet Post Mini. It will arrive flattened, but please understand that it will return to its original shape if you shake it gently or steam it.
